1 Be itknown hat 1. JOHN F. .HAMER, a

citizen of theUnitedStates, residing at Puk wana, in the county of-Brule and State of South Dakota, have invented a newand u se' ful Improvement in-Vaporizers, of which the following is aspecification.

. This inventlon relatesito mprovements .1n

vaporizing devices and particularly'to improvements for supplying the carbureter. or similar devices for combustion enginesv with ai mixture ofatomized liquid fuel and air. Thejinvention contemplatesthe provision of means for permittingthe discharge of exhaust gases from the fuel conduitrin the 'eventthat the engine should back-fire. V It is also an object- 0fthe present invention to-jin-itiatejthe vaporization offuel in the fuel 'tank iby the admission of atmos- Z0 ph-eric air into the tank. V Another object of the invention is further? more to. provide a connection between an air valve on the gasolene tank and'the throttle of thefengine, wherebyLupon operation of the throttle. the air valve-also ;is automatically operated.-.

With these iandother ob ects 1n vlew an embodimentofthe invention is illustratedin.

. theaccompanying. drawing and is described invthe'following specification, the novel features being pointed out inthe appendlng 7 claims. a

' In the drawings 2.

Figure 1 is a ,diagrammatical side eleva tion'and part section of the feeding device; r

Fig. 2 is a diagrammatical part elevation and part section of a modified embodiment of the device. 7 g f' The carbureter 1 may be of any suitable construction andfma'y comprise a float chamber 2 and a mixing chamber 3; the latter is connected by means of a conduit 4 with an auxiliary tank 5 containing the fuel. A valve 6 is contained in the conduit 4 for regulatin the supply of fuel from the tank improved fuel 5 orfor siutting off this supply. 'The float chamber communicates through a pipe 7 with a gasolene tank 8 of any suitable construction. Thistank has a'valve body 12 movable Within a nipple 13 which is secured to an opening in the tank. A spring 14 surrounding the stem- 15 of the valvebody and pressing the washer 16 in the stem 15 upwardly has a tendency to maintain the valve in closing position. i

When it is desired to supply a mixture of fuel and airto the carbureter the valve 6 is closed and the valve 12 opens in response to engine 'suctlon to admit air into the tank 8. The vapor of gasolene mixed with the incom ng air rises and escapes through. the conduit 7 which terminates at the float chamber2. This conduit containsa check valve perm tt ng the flow of the fuel mixture in a predetermined direction and preventing the flow of combustion gases in the op- Itwill beobserved that the-tank 5 supplies liquid fuel, which may be. atomized in 'the,;usualwa-y in the carbureter, and when desired this source of liquid-fuel maybe em ployed with the supply of carbureted air from the tank 8, by opening slightly the valve. 6. This is entirely within the option ofthe operator, and acts as an economizer, employing the otherwise dissipated gases generated in the tank 8.-

--In the embodiment illustrated in Fig. 2'

theform of the valve in thetank is slightly modified and the valve 28 is normallypressed against its seat 29by a spring 30 which surrounds the freely movable stem 31 of the valve. Thisstem is providedat its upper end with an enlargement or head 32. The bell crank lever 33 engages with one arm below the head, while the other arm of the bell crank lever is connected by a rod 34 with a second bell crank lever 35. This'sec- 0nd bell crank lever is also associated through its other arm by a link 35 with the rod 36 which usually extends through the steering post 37' and which carries at its upper end an arm 41 operating on a segment on the steering wheel and providing the hand controlof the throttle. -A finger 38 at the foot end of the rod is connected by means ofthe link 39 with a crank arm 40 for the adjustment of the throttle. Check and relief valves 42 and43, respectively, are

hereinbefore described.
